This invention relates to a sanitary closet and its object is to provideon the one hand improved hygienic conditions especially in v regard toavoiding the issue therefrom of dis- 5 agreeable or noxious gases, andon the other hand a simple construction and a simple configuration ofthe portions utilized.

An essential feature of the closet according to the present invention isthat the pan 1c is divided by an upright partition into two compartmentsone behind the other, of which the front compartment serves as a urinaland remains permanently open, whilst the rear compartment serving as theactual closet l basin can be closed by a horizontally guided slidingcover.

The sliding cover, which is located beneath the seat and suitably iscomposed of earthenware, porcelain or other similar resistant 2material, can be displaced by means of an external handle, thedisplacement preferably effecting also the control'of the water flush.

The actual closet basin can be closed beneath by a flap and is connectedto a ventila- Zv tion pipe. This ventilation pipe may be a laterallysituated continuously extending fall pipe by means of which any foulgases are constantly sucked upwards.

As the closet basin is constantly closed, empty, odourless and protectedagainst freezing, the soil pipe need merely be provided in the basement,where it is connected to the house drain, with a closure contrivance.

\Vhen conditions so demand, merely house- 'hold slops can sufiice forflushing the closet.

On the accompanying drawings, in Figs. 1 to 4 a constructional exampleof a water closet according to the invention is illus trated, and inFig. 5 the application of the invention to a dry closet is shown. Inthese drawings Fig. 1 is a side elevation;

Fig. 2 a section taken along the diverted line AB of Fig. 1;

Fig. 3 a plan, and

Fig. 4 a vertical longitudinal section;

Fig. 5 is a vertical longitudinal section on a smaller scale showing thedry closet.

In the construction shown in Figs. 1 to 4, the pan 1, which is fittedinto a socket 3 of the 279,798, and in Germany March 31, 1928.

soil pipe 4, is divided by an upright partition 5 into two compartments.The front compartment 6, which is intended for urination, remainsconstantly open and is closed at the bottom by a ball valve 7 The rearcompartment constituting the actual closet basin 8 is closed by asliding cover 9, which is horizontally displaceable beneath the upwardlylifting pivoted seat 10. The displacement of the sliding cover, which iscomposed of a water and acid resistant material such as porcelain andsuitably has a rearwardly slightly upwardly sloping upper surface, iseffected by a handle. In the construction illustrated, the handleconsists of a knob 11 situated laterally beneath the seat, and isprovided on a rack 12. Lateral links 13 connected to this rack 12, whichas shown in Fig. 2 slides on a dovetailed guide 14, engage by means ofpins or studs 15 in holes in the sliding cover 9, so that ondisplacement of the rack 12 the cover is displaced therewith, without anabsolutely rigid interconnection of the two parts being provided. Thecloset-basin 8 is closed at the bottom by a flap 16, which can be turnedover intermittently from the exterior, after use of the closet, by meansof the weighted arm 17 (Fig. 1), whereby the upper side of the flap withthe excreta becomes directed downwards and permits the latter to dropoff, whilst the previously clean underside ot'the flap becomes directedupwards.

. The rack 12 gears by its teeth with a pinion 18 (Figs. 1 and 2), whichis so mounted on the plug 19 of a cock which controls the water flushthat whenever the sliding cover 9 is closed or opened the flushing wateris turned on and off, so that the basins 6 and 8 are thereby flushed. Inaddition the basin 6 can be independently flushed by water from a branchpipe 21 (Fig. 3), controlled by hand by a knob 20 (Fig. 1).

Connected to the. vertical fall and ventilation pipe 22, which suitablyis located at the side ofthe closet, is a ventilating pipe 23, leadingto thebasin 8. Below in the soil pipe 4 ventilation is provided by abranch pipe 24. The ventilating branch pipe 23 can be closed by abutterfly valve33 which is positively con- 1 nectcd to the sliding cover9. The handle 11 for displacing the sliding cover and the handle 17 fordisplacing the lower closure flap 16 may be positively interconnected.

Fig. 5 illustrates a dry closet constructed in accordance with theinvention. Here, as in the water closet, the pan is formed with twocompartments or basins 6 and 8, of which one 8 can be closed by thesliding cover 9 displaceable from the exterior. In a casing 25,supporting the basins 6 and 8, is contained a receptacle 27 forreceiving the excreta, this receptacle being introduced and withdrawnthrough an opening, capable of being closed by a door or flap, in thewall of the casing, conveniently an opening 26 in the rear wall thereof.For receiving urine draining from the front basin 6, is provided aseparate receptacle 28 loosely thrust into place from the front. Thisreceptacle 9 8 can when necessary be easily removed and emptied. Thereceptacle 27 is removed after pushing the closet away from the Wallagainst Which it stands, after the pipe section 32 of the closet formedwith a socket 29 has been disconnected from the fixed ventilating pipe31. For purposes of ventilation a branch pipe 30 leads from the pipesection 32 to the basin 8. Gases ascending from the receptacle 27 belowalso have access. The ventilating pipe can at times be closed by abutterfly valve 34. In the form shown in the drawings, the dry closet iseasily transportable, so that it is capable of manifold use. It can beused with all kinds of sewers by substituting a hopper for thereceptacle 27.
